Apigenin reduces LPS-induced apoptosis in the lungs. Lungs from mice treated with LPS, control, apigenin (Api) or apigenin 3 h prior to LPS (Api + LPS) were obtained at 24 h. (A) The number of apoptotic cells was determined by the TUNEL assay and expressed as the mean ± SEM of the numbers of stained cells per 1000× microscopic field (cpf) (N = 4 mice for each biological condition; * p < 0.01 vs. LPS), scale bars: 25 μm for all figures; (B,C) Caspase-3 activity was determined by the DEVD-AFC assay using lung lysates as described in materials and methods. Values represent the means ± SEM (N = 4 mice for each biological condition; * p < 0.05 vs. LPS); (D) Lung tissue immuno-histochemistry using antibodies specific for active caspase-3 in combination with anti-CD31, anti-cytokeratin or anti-7/4 antibodies specific for epithelial, endothelial and neutrophils, respectively. Scale bars, 100 μm.
